Geoworks Partners with Optimay

ALAMEDA, Calif./MUNICH, Germany (Jan. 20, 1998) - Geoworks Corporation
(NASDAQ: GWRX), a leading provider of wireless software and service
solutions, and Optimay GmbH, a subsidiary of Lucent Technologies (NYSE:LU),
announced today that they have joined forces to help manufacturers to
develop in record time enhanced GSM phones, which combine traditional
wireless telephony with the ability to handle more complicated features
such as data services, email or value-added applications. In the
collaborative effort, Geoworks' Premion Interface+, a state-of-the-art
graphical user interface (GUI) and over-the-air application platform based
on the Wireless Application Protocol standard, has been integrated with
Optimay's GSM Phase 2 Protocol Stack.

Together, Geoworks and Optimay will create a graphical phone reference
design that offers manufacturers the technological foundation for building
easy-to-use, enhanced phones for GSM networks around the globe. The bundled
solution also offers handset manufacturers the ability to roll out
industry-leading wireless handsets to market in record time.

Through Optimay, manufacturers will get a complete reference design
solution with Protocol Stack software for the GSM network, enabling new
manufacturers to enter the competitive GSM market quickly. Existing GSM
manufacturers can quickly expand their product offerings. Optimay is one of
the first companies to supply GSM software, which enables tier 2 and tier 3
manufacturers to achieve Phase 2 Full Type Approval.

"Optimay strives to provide complete solutions to our customers from
hardware and GSM software to integrating third-party value-added
technologies", said Sam W. Goodner, president and CEO of Optimay. "By
joining forces with Geoworks, we are now also able to offer our customers
an integrated solution for enhanced wireless handsets, which will enable
our customers to have a broader selection of technology choices."

Geoworks' contribution is its Premion Interface+, which combines
Man-Machine Interface (MMI) and WAP browser technology into a single
package, eliminating the software redundancy that comes from having a
separate WAP browser. The resulting software efficiency also makes the
phone easier to use by eliminating the need for the special data mode found
in existing smart phones. Premion Interface+ gives service providers
greater branding and target marketing opportunities, provides manufacturers
with the ability to develop product lines utilizing advanced functionality,
and makes it easier for consumers to use their wireless phones.

"This collaboration between Lucent's Optimay and Geoworks opens exciting
new avenues for OEMs with an eye on the enhanced phone market," said David
Grannan, president and CEO of Geoworks. "The integration of Optimay's
type-approved protocol stack and Geoworks' flexible interface sets new
standards for product line design. Together, we are committed to making
future technology available for GSM mobile phone manufacturers."

Grannan added, "Subscribers benefit, too. When you seamlessly blend
WAP-based services into the phone's basic features to the point where users
don't know if a feature is programmed in the phone or downloaded
over-the-air, you eliminate a lot of user confusion."

According to the GSM MoU Association, GSM currently has over 120 million
users worldwide and is available in 120 countries/areas of the world.
